A method for operating a powertrain of an autonomous vehicle is described. In one example, the autonomous driver may supply a torque request and a torque or power urgency assessment to a powertrain controller. The powertrain controller may monitor vehicle control system parameters based on the driver demand torque and the torque or power urgency assessment.

A driving control apparatus for a vehicle includes: one or more external sensors, one or more vehicle sensors, a steering device, an acceleration/deceleration device, an output device, a communication circuit, and a control circuit. The control circuit detects a failure associated with autonomous driving while the vehicle performs the autonomous driving, outputs the warning signal for a transfer of control of the vehicle by using the output device for a first time interval, when the failure is detected, controls the acceleration/deceleration device for a second time interval after the first time interval to reduce a travel speed of the vehicle to a target speed, and controls the steering device and the acceleration/deceleration device after the second time interval to maintain a travel lane of the vehicle with the travel speed lower than the target speed.

A power supply device for a vehicle includes first and second power supply systems, a switch, and first, second, and third mode controllers. The first power supply system includes: a first power supply including a first power storage and a first generator, and an electrical apparatus. The second power supply system includes a second power supply. When an SOC of the first power storage exceeds a lower limit, the first mode controller supplies electric power from the first power supply to the electrical apparatus. When the SOC decreases below the lower limit, the second mode controller supplies electric power from the second power supply to the electrical apparatus via the switch. When an abnormality is detected to have occurred in the switch during the second power supply mode, the third mode controller supplies the electric power from the first power supply to the electrical apparatus.

A vehicle control device includes at least one processor configured to perform operations including: performing a function related to autonomous driving based on a sensor signal from a sensing unit of a vehicle; autonomously driving the vehicle based on performance of the function related to autonomous driving; in a state in which the vehicle is autonomously driven, receiving an update request related to a first sensor of the sensing unit from a communication unit of the vehicle; determining presence of a second sensor configured to provide the sensor signal for performance of the function related to autonomous driving; and in response to reception of the update request, updating information related to the first sensor based on presence of the second sensor.

Systems and methods for operating a vehicle that includes an engine and an integrated starter/generator are described. In one example, torque generated via the engine is based on a requested driveline torque and a torque of an electric machine when degradation of an engine sensor is present. The torque generated via the engine may be adjusted responsive to a requested engine torque and a feedback engine torque that is based on output of an engine airflow sensor.

A device for assisting in the driving of a motor vehicle includes a line detector for detecting the boundary line of a traffic lane, a setup module capable of establishing a virtual lane from the line detected, a monitoring module capable of monitoring the risk of the motor vehicle leaving the virtual lane established. The device also includes a module for acquiring an image representing a relevant object. The setup module includes a first map containing values of a position of a virtual-lane boundary according to a lateral shift of the relevant object in the acquired image.

A safety stoppage device for an autonomous road vehicle having at least one control network and sensor, and an autonomous drive-control unit for processing sensor and communication signals and providing control signals for lateral and longitudinal control. A primary brake-control unit is configured to monitor the longitudinal control signals for faults and, upon determination of a fault, execute a longitudinal control profile, stored independent from the autonomous drive-control unit, to perform braking to a stop. A primary steering-control unit is configured to monitor the lateral control signals for faults and, upon determination of a fault, control a primary steering actuator to follow a lateral control trajectory, stored independent from the autonomous drive-control unit, and, if not already triggered, simultaneously trigger the primary brake-control unit to execute the stored longitudinal control profile to control wheel brakes to perform braking to a stop during execution of the lateral control trajectory.

System and method for controlling operation of a vehicle in real-time with a supervisory control module. A fault detection module is configured to receive respective sensor data from one or more sensors in communication with the vehicle and generate fault data. The supervisory control module includes at least one fault-tolerant controller configured to respond to a plurality of faults. The supervisory control module is configured to receive the fault data. When at least one fault is detected from the plurality of faults, the supervisory control module is configured to employ the fault-tolerant controller to generate at least one selected command. The selected command is transmitted to one or more device controllers for delivery to at least one of the respective components of the vehicle. Operation of the vehicle is controlled based in part on the selected command.
